Unit runs continuously--won't shut off?

When trying to use my Hayden Model 3600 central vac when trying to turn on the unit runs for 1 or 2 seconds and shuts off and continues to do so while switched on. I have thoroughly cleaned the filter and dirk canister but the intermittent running still occurs. Any suggestions?

I need a relay board for a Nutone CV 450 12.6 amp dual motor vacumn unit. Where can I locate one? Part #??? Unit will run by itself, then shut off. Unit wll not run at all. It has a mind of its own. Crossed a couple of wires on one of the relays and the unit runs smooth as silk. I assume its the relay, but can't locate part number.

I have an easy flo vacuum model # 199C and it won't shut off. It started out as an intermitent problem but now will not shut off when the hose is unplugged, nor when the off/on switch on the main unit is shut off. the only way to get the motor to stop running is to unplug the unit. Any ideas?

Just had this same problem. I unplugged the low voltage signal wires and the vacuum stayed on. Thus eliminating the possibility of the signal wires shorting out somewhere. I'm not really sure which wire(s) were causing the problem. But when I disasse ...

Model # 5770 the brush motor runs and shuts down after a few seconds...Turn unit off and the brush again will run for a second or two...If I don't turn unit off brush will not start up..Could it be the printed board..the motor brushes..or the wiring that goes from the printed board to the main motor...Thank you

Seems like your unit goes into failsafe because it detects something wrong. Well you should check the brushes and replace them if they are worn out. Also check the wiring for shorts etc, becaue the unit maybe tripping due to an overload. The printed ...

Runs for about 30 seconds then shuts off, runs for another 30 then shuts off...continues to do this

Kenmore canister model 116.25513506 wont turn on. when handle switch is turned to floor. vac motor does not turn on. When switch is turned to carpet, floor nozzle works but vac motor does not. I checked fuse, all o.k. checked continuity for plug, o.k. removed wires for bag full switch...motor wont run. I wired motor directly power cord...motor runs. Thinking it must be the circuit board, how do I bypass it or test it?

We have a Bissell Proheat 2X (model 8920). The problem we are having is when water/soap is initially released (all settings) it continues to leak out the front water spray nozzles unit the water containers are empty. The vacuum works but can't keep up with the continuous water leaking out. Do you have any idea what is sticking open to allow the continued release of water when the machine is running? Thanks Rick

Return it. It is faulty and should not do that. Mine does not. Does require changing water about evrery 10 minutes but one can see the filth in the water. Also re-clean with plain water over areas that were cleaned to remove all cleaner. Old cleaner ...

Once the unit runs it sometimes does not want to shut off. This happens regardless of the port used. If I unplug the unit it will usually seem to reset after a while and then may or may not work properly.

Lux legacy my vacuem wont run but 1second after i push the on switch. the full bag light comes on when it shuts off.i turn it on again and it runs for asecond and cuts off. it has abrand new bag in it.i tried adjusting the suction knob on top to no avail.

Actually the problem is inside of the canister itself. You need to change a part called the control valve. Occaisonally when fine particles get inside of the valve it damages the inside of the valve, sending a false reading to the main motor, causi ...

Any help would be appreciated.

NuTone CV750 Central Vacuum won't shut off. The on/off switch on side of unit has no effect. Did continuity test on switch, it tests ok.
I've disconnected the low voltage wiring at the side of unit, that had no effect.

I will assume that you disconnected the switch from the circuit when you did the continuity test -- that is really important.\015\012If so, then i think that the relay inside the top of the unit is stuck on, or the low voltage wires (inside the ...

I have Nutone VX550C. Motor runs intermittently (cycles on and off rapidly--the light on the handle is blinking furiously) when I use the on/off switch on the hose. This happens at all of the wall connectors, so suggests a hose contact problem. Motor runs continuously when I turn it on at the switch on the wall unit.

The unit does have a switchs the PVC outlets, and it sounds like the hose mech to operate the switches is broken, and intermittently making contact. A replacement hose would likely fix the problem. Looked them up on the net, and they're not che ...

Over heating Light Comes on as soon as I try to turn the unit on. I have a Miele S558 Silver Moon vacuum that has only been used once and it shut off and will not come back on. The overheating light comes on as soon as I try to switch speeds on the handle or turn the unit on at the canister, and the vacuum will not run. Do you have any idea what the problem is?

While sucking air out of the space saving bags the vacuum would not shut off when done. The unit only works when plugged in. Disconnected the low voltage wires and unit still runs, on/off switch does nothing.

Have you replace the afterfilter? It may also cause this if rather dirty. It's located under the tool caddy/air diffuser on the back half of the machine.\015\012Try this: Disconnect hose, turn on vacuum. Does it continue running? If so, pl ...

Nutone Broan CV556 runs continuously and will not shut off until I unplug it..
I disconnected the low voltage wires and it still runs when I plug it in.
Inside the top of the vacuum are 3 electrical devices - one looks like a transformer wire -- one is a rectangular electronic black box. The third is an on off rocker switch.
Which piece it likely to be shorted out? It is about 8 years old.

Series 6500 motor shuts off, vacuum continues to run, not suction

It's tripping the temperature overload in the motor. The most common cause for this is a clogged hose. Take the hose loose and attach it to the exhaust port under the back cover. You should be able to see if it's clogged and unclog it. I might also s ...

My unit powers up but does not run for more than 10 minutes before shutting down. I also sem to have lost suction. What do you suggest I do?

The air passages inside the head are plugged and causing the motor to overheat. Remove the bottom plate and look for wads of hair or other debris jamming the passages. Same procedure on the bag end (but no plate). Don't run it longer than required fo ...

It's making a very loud noise when running. I have a Bissell Quicksteamer series 2080. When I was using it yesterday it was making a light squealing noise then it turned into a loud racket. I shut it off and and cleaned the brush (lots of dog hair on it) But the racket continued.
